Ok this should be an easy question. I've had my LT for about a year and wear my new helmet just long enough to get through a helmet state. I finally broke down and bought the speakers and mic and retrofitted my helmet. I've looked all thru my manuals and can't find how to turn off the external speakers of my stereo so only the helmet speakers play. I know this sounds basic but can't seem to find it in the manuals. Sorry for the trivial question. I've completely taken the tupperware off and added different farkles (unrelated to my question here) and yet something as simple as this has got me stumped. Btw, it does sound great in the helmet. Just don't want to have to turn it down at stoplights since the external speakers continue to play for now.
